reverse affricates?

[Jordan Lachler]

Dear List Members,

While combinations of a stop and a following fricative are often treated as
single phonemes in languages, are there cases of the reverse sequence, a
fricative plus a stop, being treated as a single phoneme?  In Keresan, the
only (native) consonant clusters are of the type fricative +
stop/affricate.  Moreover, the place of articulation of the fricative is
wholly determined by the place of the stop/affricate; i.e. the fricative is
retroflex <sr> before bilabials and velars, and alveopalatal <sh> before
all other places.  Davis (1960) in his grammar of Santa Ana Keresan
implicitly treats these fricative+stop/affricate clusters as being on a par
with "simple" consonants.

I would be interested in hearing about other languages with a similar
relationship between fricatives and stops, as well as any theoretical
discussions on the likelihood of such segments.  I will be glad to post a
summary of responses.

Thanks very much!
